Node operation failure.

Variants

UnknownDb(String)

Named database does not exist.

InvalidName(String)

Database name is not storable.

UnsupportedFormat

Database root uses a storage format newer than this binary.

Fields

found: u32

Version found in the root.

supported: u32

Newest version understood by this binary.

Deposed(String)

This node no longer holds the write lease.

Standby

This node is a warm standby for the database; the lease holder serves it.

Fields

db: String

Database name.

owner: String

Current lease owner id (empty when unknown).

endpoint: String

Owner’s advertised client endpoint (empty when unadvertised).

Codec(CodecError)

Payload failed to decode.

TxForm(TxFormError)

Transaction forms failed to convert.

SchemaForm(SchemaFormError)

Schema forms failed to convert.

Transact(TransactError)

Transaction pipeline failure.

Store(StoreError)

Store failure.

Log(LogError)

Log failure.

Lease(LeaseError)

Lease failure.

BadRequest(String)

Malformed request.

BasisMismatch

A conditional transaction was prepared from a stale database value.

Fields

expected: u64

Basis supplied by the caller.

actual: u64

Basis current when the request reached the commit queue.

GroupCommit(String)

A group-commit batch aborted after preparation (durable append, ownership fence, or metadata publish failed); every batched caller receives this so it retries. Carries the originating error’s text because the underlying store/log errors are not cloneable.

Trait Implementations

impl Debug for NodeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for NodeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for NodeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
